KATY RUMETSCH, OF SAN FRANCISCO, CALIFORNIA.

KEY-HOLE GUARD.

SPECIFICATION forming part of Letters Patent N... 345,396, dated July13, 1886.

Application filed April 15, 1886.

To all whom it may concern.-

Be it known that I, KATY RUMETSOI'I, a subject of the Emperor ofGermany, residing at San Francisco, in the county of San Fran cisco andState of California, have invented a new and useful Key-Hole Guard, ofwhich the following is a specification.

My invention relates to that class of devices that are employed toprotect the key-hole of a door and prevent the look from being picked;and my invention consists of two half-round rods or bars jointedtogether at suitable intervals, the flat sides of which move one uponthe other when thrust through a key-hole, andform a projecting toe uponthe opposite side of the 'door, in which position it is held by a keypassing-through opposite slots in the guard.

Referring to the accompanying drawings, forming a part of thisspecification, Figure 1 is a side view of my key-hole guard with the twoarms shut down ilatwise, the one upon the other. Fig. 2 is a side viewof the same as applied to a key-hole.

The two arms a and b are composed of a half-round or nearly half-roundrod of' metal. The two flat portions of the rod are placed face to face,and are connected at their outer ends by a rule-joint, 0. Near thecenter of the lower arm or arm, a, is formed a joint, d, which permitsthe connecting portion of the arm to move only at right angles to andperpendicular with said lower arm. A joint, 0, is formed in the arm I)at a point nearly opposite the joint (I of the arm a, and of the samecharacter as that of d, and midway between the joint 6 and the end jointis formed a knee-joint, f, so that the two sections may easily be foldedtogether when the toe or foot is formed at the end of the rod, as shownin Fig. 2. A small flat spring, 9, is connected to the arm I) just infront of the joint f, which lifts up that portion of the arm from thearm a at that point, so that the end loop or toe can be easily formedwhen the guard is inserted in the key-hole. A clip, h, is connected toSerial No. 199,014. (No model.)

the arm a,which embraces the arm I) and holds the two arms together,forming a slide for the upper arm along the lower arm.

In practice, when the guard is in the posi- 5c tion in the key-holeshown in Fig. 1, by placing the index-finger of the hand in. the loop 2'upon the lower half of the guard a, and push ing with the thumb againstthe curved arm j at the end of the arms I), this arm will slide alongthe arm a until the two jointed arms of b are I folded up and assume theposition at the opposite side of the door or key-hole, the door havingbeen previously locked by the ordinary bolt, and forms theupwardly-extending foot or toe, as shown in-Fig. 2, when a key, K,-isplaced in the parallel slots Z Z, formed through both arms, and apadlock inserted through the hole in thekey K, and the first section ofthe jointed arms a folded down, which prevents all access to the lock orbolt of the door through the keyhole.

Having thus described my invention, what I claim, and desire to seen reby letters Patent,

l. The combination of the arms a and b, 7 jointed together at the outerend and clipped together at the opposite end, and the retaining-key forthe arms, said arm a consisting of two sections jointed at d, said armI) consist- 7 ing of the sectionsjointed at e and f, and the saidsections a I) being further provided with slots Z l for theretainingkey, substantially as specified and shown.

2. The combination of the sectional jointed 8;: arms a and I), havingopposing flat faces, said arms beingjointed together at one end,elippedtogether at the other,and provided with curved handles 1 and j, theinterposed spring 9, and the key adapted to pass through slots in thearms, as shown and set forth.

In testimony that I claim the foregoing I have hereunto set my hand andseal- KATY RUMETSOH. [L. s]-
